Why is my fan working loudly after a liquid spill?

I picked up the laptop, but due to recently having grown my hair, it was wet and a small amount of water entered the left side, when open in front of you for typing. The screen flickered so i closed the lap top and left it to dry overnight. The next day the computer worked fine, but now the fan makes a loud noise, and it seems a bit slow.
